Cluster Analysis: Classifying Romano-British Pottery and Exoplanets
Pages 20

The data shown in Table 18.1 give the chemical composition of 48 specimens of Romano-British pottery, determined by atomic absorption spectrophotometry, for nine oxides (Tubb et al., 1980). In addition to the chemical composition of the pots, the kiln site at which the pottery was found is known for these data. For these data, interest centres on whether, on the basis of their chemical compositions, the pots can be divided into distinct groups, and how these groups relate to the kiln site.
